Oracle按最大日期加入子查询

Question

我有一个查询如下，这个查询有一个子查询得到 具有窗口函数的最大日期。此子查询的工作方式类似于没有其余查询的魅力。但随着查询的其余部分;它不会返回所需的结果。

问题是结果集具有多个具有相同CALLID的行（CALLEXSERVICESALE次数）。

查询;

当前结果集;

EC.* (same data)       20/10/2015 15:08:50       SALE CANCELLED
EC.* (same data)       20/10/2015 09:12:30       SALE COMPLETED

期望的结果集;

EC.*        CESS.AUDIT_CREATE_DATE    LCESS.NAME

EC.*        20/10/2015 15:08:50       SALE CANCELLED

其中audit_create_date是最新的。
